    No, I had sent it a few days ago. But overall they were quite quick.
    I didn't mean to scare anyone, there are plenty of working Phoenix mods and I'm sure the tools and modders get better all the time.

    Personally I will wait until the new method Yen talked about will be widespread, hopefully in the form of a tool.

    Acer Aspire 5630 dead

    I tried all BIOS Recovery procedures, nothing ... the notebook is DEAD, pressing the power button does nothing, no fan, no led, no keyboard, and no hd/floppy/dvd/usbpen working...

    Thanks for the suggestions. When I try to power on the machine nothing happens. Fan doesn't turn on, etc.

    Nothing happened when you pulled the battery, pulled the power, hit and held the esc and fn keys, plugged in power (with the fn & esc held) and then pushed power (with fn & esc held) ? Could also be fn & b keys or Win and b.

    Be very depressing if none of these worked.

    As for the cause, seems Phoenix Bios Editor pads FF hex to the first 20000 hex bytes of the bios file it produces. Acer has some sort of data in the first 14000 hex bytes that this padding overwrites. Not sure if this is the only problem or not.

    I have tried patching the acer 20000 hex header onto the bios editors output file, I am just not brave enough to flash my acer laptop to see if it works.

    Don't use PBE. Do/get an SSV2 mod.

    You need to buy a USB floppy drive and floppy disk, w/o those tools is just impossible to recovery your notebook.

    This is not true.
    I compared a Modded By myself BIOS and the original the first 14000 bytes are the same.
    When using PBE you should before modding get the checksum of all the modules.
    After modding and generating a new BIOS get the checksum of all modules.
    Also make sure they are no dissemble errors or built errors
    The only changes you should see is the modules you have changed + Romexec00.ROM.
    Other modules should have the same checksum especially bb.bin or bb.rom
    You should only attempt to flash if the modded BIOS meets the criteria above.
    Also hex edit the modules in TEMP folder directly.
    Mark the offset before changing to make sure you didn't add any extra bytes or missed any.
    If you find other modules which you didn't touch changing you should consider abandoning the modded BIOS and redo if the same result occur find other modding methods.
